A good man

Link:

The owner of a café in the center of Madrid, Spain has become a hero of sorts and internet phenomenon after standing up to riot police and allowing protestors to seek refuge in his establishment. The incident took place yesterday, when thousands of protestors took to the streets to demonstrate against the government of Spanish Prime Minister Mariano Rajoy.

The man, Alberto Casillas, tells Eco Diario that he saw the whole drama unfold near the Neptune fountain, when police finally charged protestors and people began to flee the scene. “I saw a boy who was being beaten up by the police — he was bleeding — and I went to help him,” said Casillas, who let protestors inside his café. “I then stood in front of the restaurant and didn’t let the riot police in.” He also fed all of the protestors that had flocked to his business.

Images from the edge of a black hole:

An important thing to remember about science is that some of the stuff we talk about in the general public as “fact” — like, say, black holes — haven’t actually been seen by anybody. Instead, black holes exist on paper, as part of theoretical astrophysics. They also exist in indirect evidence — we can look for things in the universe that should exist in a certain way, in a certain place, if our theoretical astrophysics is correct. So far, that lines up, too.


And then there’s this thing. Like I say, it’s not a photo. It’s more like a model. Telescopes — the kind we point at deep space — don’t collect images, they collect information. This is a digital rendering made based on information collected when researchers pointed four different telescopes at a galaxy called (poetically) galaxy M87. What you’re looking at (in the big image) is a jet of photons shooting out of galaxy M87. The smaller picture is a zoomed-in shot, showing massive ribbons of gas undulating and spinning around the something at the galaxy’s center. If the theoretical astrophysics is right, this is the closest we’ve ever gotten to seeing a black hole.
